Kirk fights aliens with his bare hands all the damn time. You know he's got balls of steel AND experience. The guy has a phaser and he still gets in more fights with his fists and people are choosing to fight him over the nerd?

Kirk is human. Spock's "human side" was thought to be a DOWNFALL in Vulcan eyes. Vulcans are strong as fuck and I would shit myself in fear trying to fight Spock. At least there is sort of a chance fighting another human.

Neither will Kirk, unless you're out to kill other people - in which case Spock would still be quicker to kill you, because it would be more logical. Remember which one has compassion, and which is just acting as a pacifist.

Spock is way stronger because he's a Vulcan. He can make you pass out by touching your shoulder. His emotions won't get in the way. If some lady walked by, Kirk would be distracted for a minute, giving me the perfect time to punch him in the face.
